We have a donor who has had several Invalid Results due to Abnormal PH with no reasonable explanation from the donor.  She does take several medications.  Could the combination of medications possibly be causing the invalid results?  She is currently taking:

bulletMetoprolol
bulletLovastatin
bulletLorazepam
bulletFurosemide
bulletNifedipine
bulletPrilosec
bulletLexapro, and
bullet Aspirin

Any input would be greatly appreciated. I have looked at other Q&A's on this forum but did not see these particular medications listed. The donor has spoken with her physician who says that her pH level is fine on the in-office testing they have done for her.
